SAMUEL A. OANFIELD, OF GARLSTADT, NEW JERSEY.

IMPROVED BED-BOTTOM.

Specification forming part of Letters Patent No. 54,292, dated May 1, 1866.

To all whom it may concern:

Beit known that I, SAMUEL A. CANFIELD, of Garlstadt, county of Bergen, and State of New Jersey, have invented a new and useful Spring-Bottom Bedstead; and I do hereby declare that the same is fully described and represented in the following specication and the accompanying drawings, of Which- Figure is a top view of my improved springbottoin bedstead Fig. 2, an under-side view; Fig. 3, a longitudinal section 5 Fig. 4, a transverse section. Figf5 represents a front view of one of the end or sustaining bracket-plates, which I intend to use in connection with my improvement instead of a series of brackets, as represented in the drawings. Said bracket-plates may be composed of wood or iron. Fig. 6 is a sectional view of the said bracketplate.

The nature of my invention consists in an improved mode of constructing the bottom of a bedstead with all the elastic properties for adaptation of itself to the motions of the occupant that is possessed by the most complicated and expensive spring-bedsteads heretofore introduced, and at a very small cost; and this desideratum is attained by afixin g to the head and foot portions of the 'frame of the bedstead a series of stationary arms or brackets, there being laid on each of said series a stout band or sling composed of vulcanized india-rubber of the necessary width and thickness to sustain, with the bed, the weight of two or more persons, the ends of said bands being fastened to the extreme brackets of each series, and upon the said bands are laid,respectively, the ends of the slats, which form the bottom of a bedstead.

Having explained the nature of my invention, I will proceed to describe its construction and operation.

In the drawings, A A represent the head and foot, and B B the side portions, of the frame of a bedstead.

c c, &c., represent the series of arms or brackets, which are firmly affixed to said head and foot frames, A A, or, instead thereof, the

` metallic bracket-plates shown in Figs. 5 and 6 of the drawings.

D D are the india-rubber bands or slings passing over the arms or brackets e c, and on bearings or recesses provided for same in said brackets, the ends of said bauds being secured to the extreme brackets of 'each series by being introduced through slots in and wound around said extreme brackets to produce the necessary tension.

F F, &c., are the slats, composed of ash wood or other material having a spring in itself, forming the bottom of the bedstead, which may be of any desirable number, one in each space between, and determined by the number of brackets, and the two ends of which, respectively, rest upon the bands D D, said bands forming an elastic or spring bearing for same, which will offer only a partial resistance to any pressure that may be brought to bear upon them, and upon the pressure being removed will resume their former position in relation to the slats, as shown more especially in Fig. 4, and, in conjunction with the natural spring contained in the slats, will form an admirable spring bed-bottom. the slats being confined in their respective places by rods g g, which pass over them, and are crank-shaped at their ends for the purpose of descending belowT the frames B B and retaining the slats in position.

h h represent a series of loops of cord carried from bracket to bracket on the under side, of a given length to prevent any undue tension of the bands D D that may arise from a sudden strain or pressure.

From the above description it will be seen that by my device I produce a spring-bottom for bedsteads, which, while it is of simple and inexpensive construction, combines all thel properties and possesses all the advantages yet introduced in spring-bedsteads 5 and, more over, by my device any ordinary bedstead can be easily converted into a spring-bedstead at a small expense by afixing the bracket-plates, as in Figs. 5 and 6, to the head and foot of frame, the india-rubber bands D D, and the rods g g, thusrendering my invention available to every householder without the expense of purchasing a new bedstead.

I am aware that the slats of a bed-bottom have been hung to the frame of same by means of bands lof india-rubber, but such are not new or serviceable, and therefore I ldo not claim such; but v What I do claim as my invention, and (lesire to secure by Letters Patent, is-

The combination of the crankshaped rods g g and guard-ropes hh withv the elastic bands Dv D and recessed brackets C C, substantially as and for the purpose herein specified.

In testimony whereof I have hereunto setv my signature.
